Street. East Side local trains ran from City Hall to Lenox Avenue (145th Street). Express trains had their southern terminus at South Ferry or Atlantic Avenue and had their northern terminus at 242nd Street, Lenox Avenue (145th Street), or West Farms (180th Street). Express trains to 145th Street were later eliminated, and West Farms express trains and rush-hour Broadway express trains operated through to Brooklyn. To address overcrowding, in 1909, the New York Public Service Commission proposed lengthening platforms at stations along the original IRT subway. As part of a modification to the IRT's construction contracts, made on January 18, 1910, the company was to lengthen station platforms to accommodate ten-car express and six-car local trains. In addition to $1.5 million (equivalent to $ million in ) spent on platform lengthening, $500,000 () was spent on building additional entrances and exits. It was anticipated that these improvements would increase capacity by 25 percent. At the Brooklyn Bridge station, the northbound island platform was extended north and south, while the southbound island platform was extended south, necessitating the relocation of some tracks. Six-car local trains began operating in October 1910. On January 23, 1911, ten-car express trains began running on the Lenox Avenue Line, and the following day, ten-car express trains were inaugurated on the West Side Line. In 1918, the Lexington Avenue Line opened north of Grand Central–42nd Street, thereby dividing the original line into an "H"-shaped system. All trains were sent via the Lexington Avenue Line. With the closure of the City Hall station in 1945, Brooklyn Bridge became the southernmost station for local services that formerly terminated at City Hall. In the late 1950s and early 1960s, the New York City Transit Authority undertook a $138 million (equivalent to $ in ) modernization project for the Lexington Avenue Line. As part of the project, platforms at Brooklyn Bridge were extended. Work on the reconstruction of the Brooklyn Bridge station started on May 18, 1959. Prior to the rebuild, the station's local platform could only accommodate four cars, resulting in delays. The platforms were lengthened, widened, and straightened. Originally, the island platforms narrowed at their northern ends to an unsafe width of only five feet. The project remedied this situation, lengthening the platforms from to and widening them. The platforms were extended northward by to just south of Reade Street. In addition, a new exit was provided at Reade
